The ${}^{6}\mathrm{Li}(p,\ensuremath{\alpha}{)}^{3}\mathrm{He}$ reaction has been studied from ${E}_{\mathrm{c}.\mathrm{m}.}=2.4\mathrm{MeV}$ down to astrophysical energies by means of the indirect Trojan horse method applied to the ${}^{2}\mathrm{H}{(}^{6}\mathrm{Li},\ensuremath{\alpha}$ ${}^{3}\mathrm{He})$ n three-body reaction performed at an incident energy of 25 MeV. Coincidence spectra measured in a kinematically complete experiment show the presence of the quasifree ${}^{6}\mathrm{Li}\ensuremath{-}p$ process. The excitation function for this process was extracted from the three-body reaction cross section at low neutron momentum and compared with the behavior of the free two-body reaction cross section.
